Material characterization – a case study on fresco fragments from
«Villa della Piscina»
Frescoes’ fragments from «Villa della Piscina - Centocelle Park»
(Roma).
The site choice - objectives and achievements: • Relevant to Park
fruition, the ruins are now buried but frescoes’
fragments are kept in a repository, virtual fruition of
reconstructed painted wall would be possible.
• Fragments come from different walls, the problem is to support
their assignment to each wall.
• Pigment palette of a wall from the 2nd half of Ist century a.D.,
by means of Raman spectroscopy, LIF, LIBS e XRF (WP2), FT-IR and
PIXE (WP3) on 34 samples
• Laboratory measurements on mortars XRD, analyses with
micro-sampling (WP5)
• Geographical origin and possible dating of materials •
Realization technologies (optical microscopy and SEM,
stratigraphy) – ancient nanotechnology! • Assignment of 11
fragments to a wall on the basis of in-situ UV-
vis reflectance measurements (WP4)

Counteract bio-degrading with test of biocydes by LIF- frescoes in
«Catacombe dei SS Pietro e Marcellino, Torpignattara» -
Major achievements in laboratory tests from a fresco fragment
characterization of microbe communities present inside the
catacombs, in order to
compare with those ones detected in different hypogea around Roma
area [UniRM2]; definition and test of new strategy to reduce the
phototrophic growth on frescoes inside
the considered Catacombs by means of essential oils, which
demonstrated biocide capacity [UniRM2];
evaluation by means of laser induced fluorescence (LIF) and
reflectance of both chemical composition and color changes onto the
painted surface due to the treatment [ENEA].
The site choice – objectives [WP6, WP7]: • An important catacomb
with painted rooms,
nearby Centocelle Park. • Interest to preventive conservation of
recently
restored frescoes. • On going parallel physiologic characterization
of
bio-deteriogen micro-organisms formerly isolated in «Catacombe di
San Callisto» [UniRM1].
• Essential oils vs commercial products as biocide.
Frescoes in Priscilla’s Catacombs in Rome Laser scanners for
biodegradation analysis
P1 - subarea where the biomass appears more dense P2 – subarea
where the biomass is less dense
P3 - subarea where the bio-deterioration is not evident naked-eye
P4 - far away from the biomass area
Persistence of the fluorescence band at 340 nm in P3 possibility of
early detection by LIF of areas attacked by microorganisms not
visible in this stage
New successive colonization of other areas is visible 4 and 8
months after the first observation, due to spread of
microorganisms
Contribution to bio-attack monitoring by means of biofilm area's
circumscription by the post processing analysis of the RGB-ITR
3D
model
P1 - intense emission band at 340 nm, identifying the biological
material present in that area P2 - the emission in intensity band
at 340 decreases and a large band at 500 nm appears P3 - Band at
340 nm still present, low intensity, and band at 500 nm increased
in intensity P4 - Band at 500 nm is the only band present

Laboratory characterization of stone samples from the garden of
«Villa Mondragone at Monte Porzio Catone»
The site choice: • A Renaissance Villa, built on a former
Roman Villa, a local tuff stone «Sperona» is used on outer walls
and in the garden,
• It includes gardens with fountains and mosaics showing important
physico- chemical and biologic degradation;
• Project objectives include the development and test of protective
materials (WP5) and diagnostic and contrast to bio-degradation
(WP7)
Laboratory measurements are on going at UniTUS and ENEA for WP5 on
lapideous material from the garden, at UniRM1 and UniRM3 to check
biodegradation on sample from the fountains [WP7]. Experiments on
lapideous conservation involve the application of consolidants with
current products (polymers, siloxanes) as commercially sold and
after addition of innovative components (e.g. nano-powders).

Environmental monitoring by FBG sensors on the «Aurelian walls of
Rome» ENEA settled a demonstration site of sensors based on fiber
optics with Bragg Gratings (FBG) for monitoring structural data and
environmental parameters at the L3 tower of «Aurelian Wall» near
Saint Sebastian Gate. Periodic demonstration campaigns are on-
going with continuous data acquisition for at least one month, in
order to ascertain the effect of rain waters on different types of
wall materials (stones, brick, etc.).
Time History of continuous acquisition for 37days on the Est wall.
